 After this the first triangle recedes somewhat into the background, although it remains as an ominous presence in all the characters' minds.In Parts 2 and 3 the main narrative focus shifts to the second triangle, in which Nastasya Filippovna plays a secondary but essential role in the course taken by the relationship between the Prince and Aglaya Epanchin.Aglaya is fascinated by the Prince's efforts to 'save' the 'fallen woman', misinterpreting it as a heroic and chivalrous deed like that of a medieval knight, a "serious and not comic" Don Quixote, or the Poor Knight in Pushkin's poem who performs acts of valour in the Crusades in the name of his Christian ideal.
